No SD

I had my first no SD card error yesterday on v7.6.1. Reboot to care of it but then I relized I should have tried remounting the card to see if that took care of it without rebooting. Oh well maybe if it happens again. On v7.6.2 now so maybe it will never happen again. I also had an issue with the battery percentage dropping to 8% from 49% after reboot. I seem to remember this happening awile ago on a different kernel. The percentage crept back up to 13% and stabalized there after about 20 min. For the life of me I can not remember what thread that that problem was reported in. Other than that this kernel is still way more refined then the current CM10.1 kernel.
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
Have you re-enabled init.d scripts? Made any changes recently? Do you have any apps moved to SD card?

If this happens again , please check the contents of /log-sdcards and let me know what it says there.

Re: [KERNEL] Siyah-i777 v7.6.2 [JB]

Everything was at default. The only thing new was I installed Better Battery Stats to see if I could improve on battery.

Maybe this app is not playing well with Siyah or 4.2 in general.
[AT&T Samsung Galaxy S II SGH-I777] arkhipenko:
Re: [KERNEL] Siyah-i777 v7.6.2 [JB]

So, what's a good battery discharge rate?

I am running at average 5%/hour with a moderate daily use. Is that considered good?

(I don't particularly care for nightly discharge rate since I usually charge the phone overnight anyway).

Average 5% breaks down to around 2 to 3% idle and up to 8 to 10% with screen on.

I have Wi-Fi on only with screen on or on charger, and I have Juice Defender turning data off when off with pings every 15 min. I am on 3g, so the radio eats up some battery. 2g is more battery friendly, but slower.

Any feedback?
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
3% idle sounds a bit high to me. You may have an app that is waking your phone a bit too often. With my apps installed, sync enabled, and only GPS being disabled...I get less than 1% per hour of idle drain. You may want to check for apps that update at preset intervals, such as Beautiful Widgets (which I have recently found to be an extreme battery hog), Facebook (perhaps the worst battery drain ever), Google + etc etc. Remember that with Juice Defender installed, if an app tried to connect but it cannot connect then it will likely try to keep the phone awake until it gets some data updates.

Not much we can do about the screen on drain unfortunately, other than using lowered brightness, dark wallpapers and apps that have dark backgrounds.

Our WiFi chip drains VERY low amount of battery so it is best to leave it on all the time really.

For what it's worth - I have Juice Defender Ultimate and it seems to make my battery life worse.

Re: [KERNEL] Siyah-i777 v7.6.2 [JB]

So I checked the BetterBatteryStats... the worst partial wake lock offenders are actually Google maps, closely followed by Juice Defender.

Disabled Network location services - will see how that goes....

With Juice Defender though, is the battery saved by disabling radio worth partial wakelocks it generates?

Will run with JD disabled for a while to see if it helps.

By the way, Facebook was way down in the list. Maybe they read this thread and improved???
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
Juice Defender, in my use at least, uses a good deal more power than it saves on my phone. Not sure if disabling it will make much of a difference as it may still be loading into memory..i never really checked into that.

At some point, Facebook will use a lot of your battery if it is installed. Look not only at the wakelock% but also the number of time that it is waking up your phone.

Re: [KERNEL] Siyah-i777 v7.6.3 [JB]

I find juice defender drains more than it saves I have a limited data plan 3gigs with no WiFi at home my data and sync is always off til I need em saves a ton of battery and its quick to just toggle data on and check stuff then toggle it off as far as fb I use 3rd party fb app called FB touch it just mirrors the browser mobile page but gives u the app style look and has never hogged resources for me give it a whirl

today i was playing music then suddenly it started skipping and cutting in and out bad i searched about the issue cuz i remember it being talked about and i saw it said it was fixed i tried raising up the screen off freq for the music to 300 and then 400 and no go
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
The fix that I have seen mentioned here for music stuttering is to set Stweaks->CPU->CPU Idle Mode (Sleep Mode) to AFTR Only . Sometimes it helps to also set Stweaks->CPU->SCALING_MIN_STANDBY_FREQ to 300000khz or 400000khz .
[AT&T Samsung Galaxy S II SGH-I777] bleedingthru:

I have been having the same problem with the battery as arkhipenko. Will v7.6.3 fix this problem? Just wondering.
[AT&T Samsung Galaxy S II SGH-I777] arkhipenko:
Re: [KERNEL] Siyah-i777 v7.6.3 [JB]

AJ, in your opinion, all other things being equal, should battery life be better on v7.x vs. v5.1.1? Just kernel based.

(I.e. should I even bother? )

Thanks!
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
Changing the kernel will not magically fix things if you have wakelocks or programs that are waking up your phone.

I have no idea. I never use older ROMs that v5.1.1 works on. There have been reports that this version is better than v5.1.1, but I have not compared the 2 directly.
[AT&T Samsung Galaxy S II SGH-I777] BeenAndroidized:
Thanks for the response. I guess I'll have to figure out what is causing the drain.
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
It's usually something like Facebook, Google+, Beautiful Widgets or a weather app/widget. Anything that needs to access the internet is suspect.
[AT&T Samsung Galaxy S II SGH-I777] arkhipenko:
OK. Fair. I was asking more from the development perspective: did you implement anything in 7.x which should improve battery life.

I guess I will have to find out mysefl.

At least it seems I will have more settings to play with - 5.1.1 is so boring... :silly:

---------- Post added at 04:57 PM ---------- Previous post was at 04:52 PM ----------

In my case I am not ready to uninstall all apps for the sake of battery life - in the end I got this phone to run apps...

As long as I can get through the day on one charge with some extra cushion - I am fine. 5%/hr gives me about 17 hours from 100% to 15%

What we really need is a breakthrough in battery technology!
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
Yeah - without having compared the 2 - I will say that IF I were to go back to an older ROM that works on either v5.1.1 or v7.x I would for sure at least give v7.x a try first.

On an unrelated note...I have found the actual fix for the screen-off music...the true fix that does not involve resorting to higher power sleep modes etc etc...so even better battery life is coming soon!

I will try to find a way to incorporate it into the next version.

[AT&T Samsung Galaxy S II SGH-I777] BeenAndroidized:
Thanks AJ, I am currently backing up all downloaded apps and uninstalling them to see if I still have the battery issue. Until I find out what is draining my battery, I guess I'll have to do without those apps for a while.
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
What I did was uninstall all apps, then install 1 app every other hour and monitor how the battery life was going.

Or paste your BetterBatteryStats info here and we may be able to figure it out.
[AT&T Samsung Galaxy S II SGH-I777] BeenAndroidized:
That is what I am planning to do. Hopefully I find the culpret.

I think I am too late for that (for now) I have uninstalled at least 80% of my apps already while we conversing... :eek: But if I cannot identify it by then, I'll post the battery stat up for sure.

Re: [KERNEL] Siyah-i777 v7.6.3 [JB]

You with battery problems.

Try to reduce the first GPU step to 62 and 800v. Up from there.

If it freezes, I doubt, try 850.

Also try uc the CPU a little.

1200hz 1225v and down from there.
[AT&T Samsung Galaxy S II SGH-I777] voldomart13:
me? or the other guy above my pics?
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
Everyone should make sure they go into Settings->Sound and uncheck the boxes for Keytones / Touch Sounds / Screen Lock Sound etc as these all contribute to the AudioOut_2 wakelock. The only 1 that I leave enabled there is Haptic Feedback (tho that uses some battery also).

And the weather apps/widgets will kill your battery life unless you set a long interval between updates...no way around it folks. Anything that has to wake the phone up in order to get an update will kill your battery life...

Also, you really should disable NFC unless you REALLY need it - this is also constantly waking your phone. NFC on this phone is pretty weak and not really useful anyway.

Lastly...remember that when Pandora is running that your phone will not be sleeping.

[AT&T Samsung Galaxy S II SGH-I777] RatusNatus:
Re: [KERNEL] Siyah-i777 v7.6.3 [JB]

You both need to know that Ktoon Siyah already came with UC on it.

Beside that I always UC a little more.

There is a huge space to UC your CPU and GPU.

Enable those 50 frequencies makes things a little confused but:

The default CPU voltage on 4.33 is 1225v to 1200.

On this is 1275v that is the phone default.

I do use 1200hz - 1200v

1100hz - 1175

Then I do reduce 25 to every 100hz down...

GPU:

STEP 1

62HZ - 800V

STEP 2

108 - 850

STEP 3

160 - 900

STEP4

200 - 950

STEP 5

260 - 1000

PS. Correct me if I was wrong but 108 is NOT the default's phone step 1 frequency. I don't known why this become official here.

If you apply all those settings you'll get lost.

Change a few things and test stability.
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
The tiny amount of battery that is saved from doign this does not make up for the troubles it causes.

When I had these settings as default in alpha/beta they caused a great deal of issues. It will work fine for a few but not so well for most others.

I will add something like this to the battery saving profile. But I would recommend that users not manually change these settings.
[AT&T Samsung Galaxy S II SGH-I777] RatusNatus:
Re: [KERNEL] Siyah-i777 v7.6.3 [JB]

Roger that

Sorry if it brings you problems here.

But I didn't saw many people complaining about the default ktoon uc.

Only 2 users with problems and 1 of then only with the 1200hz frequency.

Another thing is I'm testing nightmare and it looks pretty good.

Its one of the bests for sure.

I've edited with an PS.
[AT&T Samsung Galaxy S II SGH-I777] AJ Newkirk:
No offense, but it makes no difference what the defaults were in any other kernel - unless you are using that kernel. This is a different kernel, different drivers, different voltage tables etc etc etc.

The phone actually defaults to 267Mhz for the GPU.

I left those values alone when I forked this from Dorimanx's kernel. This is what he had it set to, so I left it in place. It works well.

I will add some lowered values for those who want to push it and UV the GPU. I just do not feel comfortable advising people to change things that they may not understand or remember to change back in case of issues.

I was on 7.6.1 last night. This morning the screen with get stuck to low intensity no matter what setting i have auto or full bright. Would only work again after a reboot and few minutes later it would get stuck again. Finally figure out what causing it. in stweak if you unable LCD battery saving the screen works fine.

I understand that completely. That's what this flash & tune fetish that we have is all about!

Nightmare has been working out VERY nicely here as well. I may make it the battery profile gov soon with another tweak or 2 to that profile.
[AT&T Samsung Galaxy S II SGH-I777] Eckyx:
For all of you having battery problems, this is what I get when I follow the installation instructions to the word (reboot recovery, reset profiles) and don't touch *anything* in STweaks, not even loading a profile - default governor, default scheduler, default voltages. I leave GPS on and wifi off as I have horrible wakelocks with wifi in SHO3. My weather widget wakes the phone once every 2 hours for a weather update.

^ If drain is linear, it works out to being able to idle for about 12 days before the battery dies.

I was having more issues with popping audio so I reset everything to stock and I'm waiting to see if I still have issues. I haven't had any for the past 24 hours but I haven't listened to music for any extended period, I'll report back in if I still have further problems with everything at default settings.

I have to use extweaks because stweaks refuses to start without root. And I can not run rooted all the time.

When I restore root, all other apps which require root work OK immediately, except stweaks! For stweaks I have to jump through the hoops to get it to run (even reboot does not help! )

Seriously, it takes less time to just reinstall extweaks then to deal with stweaks. Not sure what is wrong with that application.
